United Nations
A new United Nations report finds 90 percent of the thousands of disasters over the last two decades are weather-related. The majority have been caused by floods, storms, heatwaves and droughts. Researchers with the United Nations Office for Disaster Risk Reduction (UNISDR) suggest the cost has been between $250 and $350 billion per year, i.e., total of $5 trillion-$7 trillion. The report concurs with findings of previous studies that weather disasters are on the rise compared to previous decades. Flooding, in particular, is becoming more frequent and more devastating as sea levels continue to rise.
